Figs. 20 to 26 inclusive, illustrate the sev-l eral steps in the xformation Aof a cup bymy improved machine. The scale of Figs. 1 to 7 inclusive, 12, and 16 to 19 inclusive is the same, with the exception o'f Fig. 5a, which is one andone ha f times larger; Fig. 6a, which is two'and one half times larger and Fi are twotimes larger. 'lgle scale of Figs. 8

to 11 and 13 to 15 inclusive and Fi 20 is twice that of Fig. 6. The scale of i' s. 21 to 26 inclusive is eight times that of ig. 1.

The present machine is designed to roperations in the pr uction of a two-piece paper cu or container, the body of which is formed om ablank 2, Fig. 20, com risin f a sector-of an annular ring. This ody lank is provided with score lines-21, 22, near formed from a circular disc unched from a continuous disc4 has its ge erected into a ange 20, Fi 22 g. This bottom is held against the smaller end of a conical mandrel and about that man- `17a and b which its opposite long. -curved edges respectivel 'for purposes presently to be explained. he cup bottom 30 1s of paperor t e like and said drel'and cup-bottom the body blank 2 is wrapped wit the flange edge of said bottom in coincidence with `score line 22, Fig. 22. Body blank 2 is of sufficient length to twice enwrap said mandrel-with its outer end 3 overlapping the inner end 4 of said body blank, Fig. 21. Paste or some other suitable adhesive is applied to a portion o f the inner face of body 2 just before said body iswra ped. Paste is then applied to the inner ace of the bottom 23 of the cup body and that lower edge is next rolled inwardly over bottom flange 20, Fig. 23, and finally the pasted inner face of said ed e 23 is set snugly against the inner face o said flange 20, Fig. 24. The inner face of edge 24 of the mouth of the cup body then has paste a plied thereto and said edge is rolled inwardly on score line 21, Fig. 20,' and finally folded snugly with its pasted inner face against the inside ofthe cup mouth, Fig. 26, thereby completing the formation of the cup.

The present machine is an organization of mechanisms directed to the production of the two-piece `cup, the steps in the formation of which have just been rehearsed. The several devices direct to this end are preferably mounted upon a unitary base 28. Just above said base and supported thereby in suitable bearings, 29, 31, 32 and 23, Figs. 4, 5 and 6, ismaln shaft 35. This shaft may be driven from any convenient source of power, but I preferably employ electric motor 80, which through gears, 81, 82 and worm '83 drives worm gear 84 fixed'to said shaft 35,

and 5. 11e .my improved machine is a unitary organization, for purposesof description it readily falls into three grand divisions.

The first grand division, shown assembled in Figs. 1 and 4 is directed principally to feeding the body blanks from the bottom of a stack of blanks 25, Fig. 7, l.creasing and pasting the mandrel 26. It also includes the punching of the bottom, the formin of the flange thereon and the delivery o that bottom against the end of mandrel 26, after which the body blank is wrapped about said mandrel and bottom. 4 The second grand division, shown assembled in Figs. 2 and 5, comprises principally, a rotary carrier 27, fixed to vertical tubular shaft 207, with which it rotates in clockwise direction, Fig. 2. From` said carrier rotrude horizontally, a plurality of man rels as 26. At several stations about the eriphery of said carrier, operations directe to the l production of the cup are performed.

The third grand division, shown assembled in Figs. 3 and 6 com rises another rotary carrier 37 `fixed to vertical tubular shaft 316, with which it yrotates in anti-clockwise direction, Fig.- 3. From said carrier protrude horizontally a plurality of cup receptacles or those blanks and delivering them to First grand division Body-blank feeding` mechanismf-,In the upper right hand portion of Fig. 1 this mechanism is supported on casing 34. See also Figs. 7, 8 and 9. This mechanism is slightly inclined to. the horizontal, see Fig. 7, the angle of inclination being the same as that of the cup body to the cup axis, so that the blanks are delivered to the body wrapping, mechanism tangential to the mandrel. A stack 25, Fig. 7, of body blanks 2, Fig. 20, are supported' on table 40 between guides 41, 41 and the right hand ends of those blanks, Figs. 1 and 4 project beyond said table, over and for engagement with suction feed roll 42, shown in detail in Fig. 8. Said suction roll and lower feed roll 43, together with secondary housing 46 and are driven at equal surface speed by the following means. Fixed to main shaft 35 is mter gear 47 meshingwith and driving miter gear 48 fixed to horizontal shaftv 49, Fig. l2. -To the outboard end of said shaft 49 is fixedvmiter gear'50 meshing with and driving miter gear 51 fixed to short vertical shaft 52, having bearings in brackets extending outwardly from a vertical wall of casing 34.' Arm 53 extending to the left, Fig. ing for upr1ght shaft`54, Fig. 9, and to which shaft is fixed bevel gear 55 meshing with and driving smaller bevel gear 56 fixed to one end of shaft 57 of roll 45. To the other end of said shaft 57 is fixed gear 58 meshing with feed'rolls 44, 45 have bearings in` 7, from housing 46, has a bearof roll 44. The upper end of shaft 52 and the lower end of shaft 54 are operatively connected by coupler 61 having universal joints at either end thereof. Power is communicated from gear 58 to gear 62, fixed to \suction roll shaft 63, through two intermediate gears 64, 65, Fig. 4, and gear 62 meshes with and drives gear 66 fixed to shaft 67 of roll 43. Roll 43 is urged upwardly to coaction with suction roll 42 by the usual spring impelled bearing boxes, Fig. 8, and roll 44 is urged downwardly to coaction with roll 45 by similar spring impelled bearing boxes.

Suction roll shaft 63 has lengthwise chany when that port rotates into coincidence with,v

port 72 of sleeve 7 3. Air is exhausted from the chamber between sleeve 73 and the outer casing through pipe 74 connecting with said -versely on casin casing, by some convenientknown means, not shown. p

Base 75 of housing 46 may be shifted trans- 34, Fig. 1, bolts 76, 76 being slidable in s ot 77, for adjusting the two pairs of body blank feeding rolls toward or from the conical feed rolls shown in section in Fig. 10. From rolls 44, the body blank is delivered to two pairs of successivelypacting conical rolls and thence to the pasting device and to the forming mandrel.

But prior to such delivery of the body blank, the cup bottom 30, Fig. 22, is punched from a web of paper 7 8,A Fig. 15, has a. ange 20 formed thereon and said bottom is delivered against the right hand end of mandrel 26, Figs.- 1 and 4J v Said web of paper is fed intermittently downwardly in front of cutting die 79, Fig. 13, between feed rolls 85, 86, Fig. 7. Said web feed mechanism is canted as shown in said Fig. 7, for purposes of convenience, to avoid conflict with other mechanism. Said rolls are geared together as usual and smaller roll 85 is mounted lin eccentric bearings so that by swinging lever 87 to the left, Fig. 15, said rolls may be slightly separated for threading the web therebetween. Also boxes as 88 for roll 85 are urged toward roll-86 by the usual springs as-89. Roll V86 is rotated intermittently by the following means: Roll shaft 90I has miter gear 91 fixed to one end thereof and miter gear 92 fixed to the upper end of. shaft 93. To the lower end of shaft 93 is lixed miter gear 94 v meshing with miter gear 95 fixed to oneend of horizontal shaft 96. On the other end of shaft 96, Figs. 1 and 4, disc 97 is mounted for free oscillatlon and carries spring ur ed pawl 98 for engagement with the teeth o ratchet 99 fixed to shaft 96 between disc 97 and shaft bearing 100. 170 that end of main shaft 35,

' adjacent box 29 is vfixed disc 101 in which is.

mounted crank pin 102 adjustable toward and from the center of said disc by means of screw 103. On said crank pin 102 is pivoted one end of link 104 and the other end thereof is pivoted near-the periphery of disc 97 of crank pin 102 from the axis of shaft 35.

VDirecting attention now to Figs. 1 and 13T after the web of paper 78 is delivered intermittently in front of die 79, by the means just described, punch 105 advances to the left and spring su ported presser foot 106 clamps the paper we against die 79, immediately followed by the entrance of said punch into the die, whereby a disc of paper is punched from the web. Directly following, formingpunch 107 advances to the left `and pushes the paper disc into drawing die 108 and through'that die into bottom carrier 109.

For accurately centering dies 79 and 108 relatively to unches 105 and 107, said may be slight y shifted by means of dogs as sliding within it; Said punch 105 is mounted within the left hand end 1of slide 113, of rectangular cross section, and is secured in place therein by cap 114 and which cap carries the springs. for presser foot 106, Fig. 1. Said slide 113 has in its lower portion transverse slot 115, in which slides block 116 in which is pivoted crank pin 117 of disc 118 fixed to the upper end of vertical shaft119. To the lower end'of shaft 119 is fixed gear 120 meshing with and driven by equal gear 121 xed to vertical shaft 122. Said shaft 122 has fixed to its upper end. disc 123 having crank pin 124 thereof `pivoted in block 125 adapted to slide in transverse slot 126 of slide 127, vof rectangular cross section.` Sleeve 128 passes lengthwise through slide 127 and is adjustable lengthwise therein. Forming.`

'130. Miter gear 131, also fixed to shaft 130,

drives miter gear 132 fixed to the lower end of shaft 133 connected by coupling 134 to shaft 122.

Bottom carrier 109 is adjustably supported p at the buter end of arm 135, which turns o n stud 136, and opposite said arm 135 is Geneva arm 137 which isr actuated `by pin 138 of oscillating arm 139, turning onhshaft 140. Fixed to arm 139 is gear 141 driven b segment gear 142 pivoted. at 143." Sai segment gear 142 has pin k144,engaged and actuated bycam 145 fixed to vertical shaft 146, see Figs. 4, 7 and 13. Shaft 146 has miter gear 147 fixed to its lower-end, driven by miter gear 148 fixed to main shaft 35. By this mechanism bottom carrier 109 is swung from the position of Fig. 7 to deliver the cup bottom in front of rotatably mounted head 149 of mandrel 26, Figs. 1, 4 and 5.

Plunger 150 then advances to the left, Fig. 4, and delivers the cup bottom out of carrier 109 against said mandrel head 149 and fol lows that head back into its seat in the end of the mandrel. Bottom carrier 109 having thus performed itsv function, is free to 'return-to its position before die 108, which it p resently does, opening 157 therein permitting its withdrawal over the shank-of plunger 150fwithout interference.

said Pranger 15o, is mounted on the left 'l upper end of lever 153 pivoted at 1'54. The lower end of said lever has roll 155 in engagement with the groove of cam 156 fixed to main shaft 35. v

Reverting now to Figs. 1, 10 and 11, during the forming and delivering of the cup bottom, body blank y2 is advanced bythe conical rolls of Fig. 10 to the pasting device and directly after the delivery of the cup bottom against the mandrel, is wrapped -a out said mandrel. Between rolls 44, and the Aconical rolls, table 158,is provided to support and guide the body blank. The two pairs of conical rolls are mounted on frame 159, pivoted for adjustment toward and from rolls 44, 45, on sleeve 160 fixed in the top wall of casing 34, Fig. 11.

Of the first air of conical rolls, lower roll 161, Fig. 1, is xed to shaft 162 and has miter gear 163l thereof driven byl miter gear 164 fixed to the upper end of vertical shaft 165 in frame 159. To the lower end of said shaft 165 is fixed spur gear 166, driven by larger gear 167, coaxial with frame 159, Fig. 11.

.Upper conical' roll 168 is geared to lower roll 161 and the second pair of conical rolls 169, 170 are similarly geared together while power is transmitted from the gear of lower roll 161 to the gear of lower roll 169 by intermediate gear 171. Conical rolls 169, 170 are provided with means, as ribs 172, 173 to roll 169, for forming in body blank 2, Fig. 20, creases 21, 22, on which creases said blank is later folded.

A transfer table, not shown, similar to 158,'

is preferably employed between conical rolls 169, 17 0 and mandrel 26 to guide the body blank. v v f Paste is applied to the body blank as it is passed from rolls 169, 170 to mandrel 26 by the following means: Paste receptacle 174, Figs. 1, 4 and 7, has conical roll 175 constantly engaging the paste in said receptacle. Said roll has a slight up and down movement, be-

ing mounted in oscillating arm 176 pivoted onshaft 177 and said arm carries roll scraper 178. The shaft of paste roll 17 5 has gear 179 fixed thereto, meshing with intermediate gear 180 on shaft 177 and gear 181.fixed to shaft 182 drives gear 180. Also to shaft 182 is fixed miter gear 183 driven by miter gear 184 fixed to the upper end of vertical shaft 185. To the lower end of said shaft 185 is fixed miter gear 186 driven by'miter gear 187 fixed to the left hand end of horizontal shaft 188, Fig. 4. To the other end of said shaft is fixed pinion 189 driven by gear 190 fixed to main shaftv 35. For moving paste roll 175 up and down arm 176 is pivoted to the upper end of adjustable pitman 191 and the lower end of said pitman is pivoted at 192 to one end of Large gear 167 fixed to shaft 146 drives pin-- ion 201 fixed to the lower end of shaft 202 and miter gear 203 yfixed to the upper end of shaft 202 drives miter gear 204 fixed to shaft 199. Miter gear 205 also fixedto shaft 199 drives miter gear 206 fixed to the inboard'end of shaft 197.

Second grand division -In this portion of the machine, shown in Figs. 2 and 5, the wrapping of the body blank about mandrel 26 is completed, station A, in coaction with mechanism already described in the first grand division, Also the inside of bottom flange 23 of the cup is gummed, station B, and that flange turned inwardly, station C, and then pressed against flange 20 of the cup bottom, station D, Figs. 23 and 24.

Central sleeve 207 of rotary carrier 27 has its bearing in long hub 208 of casing 34A and Vertical shaft 36 projects upwardly through and turns freely in said hub. To the lower end of said shaft 36 are fixed spur gear 209 and miter gear 210. Meshing with and driving miter gear 210 is miter gear 211 fixed to main shaft 35. Driven by spur gear 209 is equal gear 212 which carries crank pin for engagement with Geneva gear 214 for imparting intermittent rotary movement to carrier 27.

Said carrier is provided with a plurality of horizontal, radially arranged shafts as shaft 215, to theiouter end of which is fixed mandrel 26. These shafts have bearings in brackets as 216 fixed to carrier 27 and arev rotated from vertical shaft 36 through large bevel gears 217 fixed thereto meshin with and driving small bevel gears, as 218, xed to the inboard end of shaft 215. Said shaft 215 is tubular, rod 219 being slidably mounted therein.. The outboard end of "rod 219 has mandrel head 149 fixed thereto and the inboard end engages between a pair of collars the yoked upper end of arm 220, whose lower end is fixed to slide 221 having bearings in bracket 216.y The outboard end of said slide carries roll 222 for engagement with the upper end of lever 223 pivoted in bracket 224 on base 28 of the machine. Said roll 222 also engages fixed cam 225 of casin predetermined timesrod 219 is slid inwardly to yretract mandrel head 149, by means of lever 223, which is actuated by cam 226 fixed to main shaft 35. 'lo this end lever 227 pivoted at 228 has roll 229|carried by its lower end in engagement with the groove of cam 226.

For exhausting the-air fromnports 230 of mandrel 26, Fig. 5a, to pick up and retain vthe body blank against said mandrelman V,ports of valve 234 come into coincidence with corresponding ports in fixed plug 235. This plug is conneetedwith someknown source of exhaust not shown. Insome cases the port in plug 235 may be a continuous annular groove, thereby subjecting air ports 230 of mandrel 26 to continuous suction. The upper hood 236, in the central upper portion of which valve 234 is formed.

The gearing which rotates mandrel 26 1s timed to give that mandrel about two complete rotations while it dwells at station A to receive and roll up the body1 blank.

After said bod blank is rolled about mandrel 26, carrier rotates in clockwise direction, Fig. 2, to present the partially formed cup, comprising bottom 30 within the rolled up body blank, to the next station, B, where gum is 'applied to the inner face of rim 23, Fig. 22, o the lower end ofthe cup body. This mechanism is besl1 shgwn 1n Fior. 16, whereln mI app ying ro 23 is rotaibly mountedgzlzlbove large gum roll 238, constantly rotating in m dish 239. Said roll 238 maybe provided with the usual .i Scrapers not shown. Small roll'237 is fixed to one end of a shaft to the other end of .drel from station to station.

which is fixed pinion 240, driven by gear 241 fixed to one end of shaft 242 to the other end of which gum roll 238 is fixed. Also fixed to shaft 242 is bevel gear 243 driven by larger bevel gear 244 fixed to the upper end of vertical tubular shaft 245. To the lower end of said tubular shaft 245 is fixed miter gear 246 which is driven b miter gear`247 fixed to the left hand end o horizontal shaft 248. To the right hand end of said horizontal shaft is fixed miter gear' 249 driven by miter gear 250 fixed to main shaft 35. Y

When in operative position, gum roll 237 lies in the path of the partly formed cup on mandrel 26 as that mandrel travels in its orbital path about. shaft 36, Fig. 2. Therefore means are provided to swing-'that roll and its immediate connecting mechanism out of said path during the movement of said manframe 251, in which the roll shafts have their bearings, is fixed to the upper end of shaft 252 .which has its bearing within tubular shaft 245., To the lower end-of shaft 252 is fixed arm 253 connected at its outer end by' link 254 with arm 255 ,fixed to the lower end of oscillating lvertical shaft 256. Said shaft 256 has bearings in the frame which supports ports of carrier 27 are provided with die, comprisin vholder 260, an

To this end,

the gumming mechanism andhas fixed thereto arm 257 which carries at its outer end a roll for engagement with` cam 258 fixed to tubular shaft 245 about midway between miter gears 244 and 246. Thus, when the cam roll is drawn toward shaft 245 by cam 258, the gum roll head 251 lis rotated Va slight amount in clockwise directiomFig'. 2, and.,

roll 237 is swung'out of the path of the cup on mandrel26, large roll 238' being free to swing in the same direction into the enlarged portion of gum .dish 239.y Then, after mandrel 26 has reached a position of rest, 237 is swung back into coactingrelatlon with the cup thereon.

The mechanism at station C, Figs. 2, 17, 17a and 17 b, is provided for turning inwardly the bottom ange 23 of the cup. A compound an outer ring 259 within anl 4inner plug 261 Iact successively on said flange. Said ring has an inwardly beveled frontedge to encircle the cup bottom ange, and which edge as it advances onto said ange bends it inwardly. Serrated plu 261 is advanced with ring 259 and folds sai flange 23 outwardly toward bottom flange. 20, Fig. 24. Holder 260 is threade'd onto head 262 and members 259,260 and 262 turn freely as one element on headed shaft 268. To limit the forward movement of rin ed into bushing 266y bolted to frame 264.

When ring 259 has been advanced its full,

stroke,'ball race rin 267 abuts against the inner face of the ange of ring 265 and serrated plug 261 continues to advance, Fi 176, compressing springs '263 and the bal 95 259, shouldered ring 265 is adj ustably threa -x bearing permits free rotation of ring 259with the cup. Shaft 268 is slidable axially in tubular shaft 270 and is constrained to rotatie therewith by key 269. f l

For rotating shaft 268 in the same direction and at the same speed as the cup, miter' gear 271 vis fixed to tubular shaft 270 and is driven by miter gear 272 fixed to the upper end of a vertical shaftto the lower end of vwhich is fixed bevel ear. 273 driven by larger bevel gear 274 fixe to the right'hand end of horizontal shaft "275. To the lleft hand end of said shaft 275 fixed bevel gear 276 driven by larger bevel gear 277 fixed to main `shaft 35. WAFor oscillating shaft 268 axially ,collars 278 engage therebetween opposite pins portion dles shaft 282, to which 1s fixed fixed to said s aft, driving larger bevel gear 285 fixed to cam shaft 282.

The next and linal step in bottoming the cup-is performed at station D, Figs. 2 and 18 where the partly I'intu'rned bottom flange gum thereinl is laid snugly against the cup bottom fiange, Fig. 24. For this operation bevel roll 286, freely turning on the end of arm 287 is provided. Said arm is fixed to cross shaft 288,.so as to swing` roll 286 out of the path of the cup and then into the cup bottom when the cup .bearing mankdrel has reached a position of rest at station D. Below the edge of the cup bottom, fixed to shaft 289 transverse to shaft 288, is large roll 290 for supporting the cup bottom edge while the inner portion thereof is acted upon by bevel roll 286. Said roll is driven at the same surface. speed as that of the periphery of the cup with which it engages. Bevel gear 291 is fixed to shaft 289 and is driven `by larger bevel gear 292 fixed to the upper end' ofk vertical shaft 293. To the lower end of said shaft is fixed miter gear 294 driven by miter gear 295 fixed to shaft 282. For oscillating shaft 288 and thereby swinging roll 286 into and out of engaging relation with the cup, said kshaft has arm 296 fixed theretoJ and the outer end of said arm is connected by adjustable link 297 with the outer end of lever 298. pivoted at 299. Between pivot 299 and the outer end of arm 298 a roll engages a cam slot in cam 300 fixed to vertical shaft 293.

Third grand division,

wardly by the engagement of roll 222 of slid'e 221, with the upper end of lever 301 pivotedin bracket 302 on base 28 of the' machine, left hand of Fig. 5. Said lever 301 is actuated from cam 303 fixed to shaft 35, Fig. 6, by means of link 304 pivotally connected to said lever at 305 and similarly pivoted to cam lever. 306 at 307.

Said lever 306 is'pivoted at 308 and its lower end carries a roll for engagement with the camv slot of cam 303. To permit roll.

inbeard end of said' shaft bevel gear 312 is fixed. Said holder 39 and gear 312 are constantly rotated by large bevel gear 313, fixed to the upper end of vertical central shaft 38, to the lower end. of which is fixed miter gear 314 driven by miter gear 315 fixed to main shaft 35.

' Carrier 37, which supports the several cup holders as 39, has downwardly reaching-tubular shaft 316 having its bearing in sleeve 317 of the machine frame. Said carrier is. intermittently rotated by a Geneva mechanism similar to the mechanism which intermittently rotates carrier 27, Fig. 5. Gear 318 is fixed to shaft 38 and drives gear 319, Fig. 3, to which is fixed crank pin 320 for engagement with Geneva gear 321 of carrier 37, Y

At station F, Fig..3, the inside ofthe mouth 24 of the cup receives a coat-ing of gum,`by means of a gumming'mech'anism substantially like the gumming mechanism shown in Figs. 2 and 18, in connection with the gumming of the bottom flange of the cup. This gumming device of station F is driven from shaft 322 connected by miter gears 323, 324 with main shaft 35, Fig. 6, and is swung into and out of engaging relation with the cup fiange by cam means similar to 'that of said Figs. 2 and 18. f

At station G the mouth flange 24 of the cup is turned inwardly against the inside of the cup by means of a device substantially like that shown in Figs. 17' and 17a, for 'turning in the bottom fiange 23. Compound die 325 carried by shaft 326 is rotated through miter gears 327,- 328, the latter of which is fixed to a vertical shaft driven by gearing connected with bevel gear 329 on main shaft 35, Fig. 6.l

Said die 325 is reciprocated into and out of engaging relation with the cup mouth by means of lever 330. yoke varm 331 and cam 332 fixed to shaft 333, driven from main shaft 35, by gearing similar to that of Fi 17.

At station H, Fig. 3, the moutli fiange 24 of the cup is rolled down against the inside of the mouth of the cup by a mechanism substantially like that of Fig. 18 for rollingrv down the bottom fiange of the cup. Therein bevel roll 334 is swung into and out of the cup mouth, lbut no under supporting roll, like roll 290. Fig. 18, is required as the pressure of roll 334 is supported by holder 39.

At station I, Fig. 3, the cup, if perfect and complete, is discharged from the machine, Figs.'6 and 6a. To this end a duplex plunger is mounted within tubular shaft 311. One member of said plunger includes small opposite head segments 335,A Fig. 6a. fixed to the outboard end of tubular shaft 336. f The inf ner end of said shaft has collars 337 between which is engaged the upper forked end of arm 338 fixed to the inner endof tubular slide 339. To the outer end of said slide is fixed roll 340 for engagement with the upper end of lever 341. Said lever is oscillated to the left, Fig. 6 at predetermined times by cam 303 to which it is operatively connected' by link 304 and lever 306 already described in connection with othermechanism. Refer- Q ring particularly to Fig. 3 it will be seen that stem 350 of roll 340 is olset to one side of transverse center line 6-6 and that stem 351 of roll 352, Fig. 19 is offset to the other side of said center line. -The headv of lever 341 oscillates outwardl between horns '353, the opening between w nich permits roll 340 to emerge from' circular slot 354 which normally constrains said roll to .a circular path. It will be observed that the diameter of head segments 335 is less than the inside diameter 23 of the cup bottom, so that said segments .in their movement of ejection, will directly engage bottom 30, Fig. 24, thereby pushing the nished cup o ut of holder 39 and discharging it from the machine.

But, if the cup, by any niischance has failed' to receive a bottom, segments 335 will move' outward idly within the cup body and fail to discharge that bottomless body. Therefore none but complete bottomed cups will be dischargedV at station I.-

At station J.. Figs. and 19, means are` provided for clearing any bttomless cups which may pass station I. To this end head segments 342, Fig. 6a, set quartering from segments 335, are fixed to the outboard end of shaft 343 which ismountcd for reciprocation within tubular shaft- 336. The inner end of shaft 343 has collars 344 between which is engaged the upper yoked end of arm 345 xed to theinner end 'of slide 346 within tubular` 'i and moves them outwardly between horns 349, thereby advancing all four segments 335,

by segments -342, Fig. 19. Said lever 347 is pivoted at 348-on base 28 and is connected by link 355 with bellcrank lever 356 of shaft 357 the horizontal arm 358 of which carries a roll' in engagement with cam359 fixed tomain shaft 35.

This completes the operation of vthe machine and that cup holder 39 at station J then continues its intermittent anticlockwise move-l ment, Fig. 3, to station E where it receives another cup to be operated upon.
